<p>Disclosed herein are a delay latch circuit and a delay flip-flop circuit arranged to inhibit the increase in power consumption while preventing malfunction under low voltage conditions. An internal signal output circuit outputs as an internal signal an inverted signal of a data signal starting from an internal transparency start timing until an internal transparency end timing. From the internal transparency end timing until the internal transparency start timing, the internal signal output circuit outputs a fixed value signal as the internal signal. A transistor delays the output internal signal over a time period which ranges from a hold instruction delay timing to the issuance of a data transparency instruction and which includes the internal transparency end timing therebetween.</p> |
